25 ml HCl x 1L/1000mL x .200HCl/1L = .005 mol HCl. Using the balanced equation from this, how many moles of NaOh will you need to completely neutralize the HCl?
A student (m = 63 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of 0.0170 s. The average force exerted on him by the ground is +16500. N, where the upward direction is taken to be the positive direction. Fro...
A stream of water strikes a stationary turbine blade horizontally, as the drawing illustrates. The incident water stream has a velocity of +18.0 m/s, while the exiting water stream has a velocity of -18.0 m/s. The mass of water per second that strikes the blade is 69.0 kg/s. F...
A model rocket is constructed with a motor that can provide a total impulse of 25.5 N · s. The mass of the rocket is 0.213 kg. What is the speed that this rocket achieves when launched from rest? Neglect the effects of gravity and air resistance.
